Performance can be absolute. A solution can be very valuable even if it simply beats a previous benchmark.

Kaggle competitions encourage you to squeeze out every last drop of performance, while typical data science encourages efficiency and maximizing business impact.

So is Kaggle worth it?

Despite the differences between Kaggle and typical data science, Kaggle can still be a great learning tool for beginners.

Each competition is self-contained. You don't need to scope your own project and collect data, which frees you up to focus on other skills.

Practice is practice. The best way to learn data science is to learn by doing. As long as you don't stress out about winning every competition, you can still practice interesting problems.

The discussions and winner interviews are enlightening. Each competition has its own discussion board and debriefs with the winners. You can peek into the thought-processes of more experienced data scientists.

How to Get Started on Kaggle

Next, we'll give you a step-by-step action plan for gently ramping up and competing on Kaggle.

Step 1: Pick a programming language.

First, we recommend picking one programming language and sticking with it. Both Python and R are popular on Kaggle and in the broader data science community.

If you're starting with a blank slate, we recommend Python because it's a general-purpose programming language that you can use from end-to-end.

Step 2: Learn the basics of exploring data.

The ability to load, navigate, and plot your data (i.e. exploratory analysis) is the first step in data science because it informs the various decisions you'll make throughout model training.

If you go the route of Python, then we recommend the Seaborn library, which was designed specifically for this purpose. It has high-level functions for plotting many of the most common and useful charts.

Step 4: Tackle the 'Getting Started' competitions.

Now we're ready to try Kaggle competitions, which fall into several categories. The most common ones are:

Featured - These are usually sponsored by companies, organizations, or even governments. They have the largest prize pools.

Research - These are research-oriented and have little to no prize money. They also have non-traditional submission processes.

Recruitment - These are sponsored by companies who want to hire data scientists. These are still relatively uncommon.

Getting Started - These are structured like featured competitions, but they have no prize pools. They feature easier datasets, plenty of tutorials, and rolling submission windows so you can enter them at any time.

The 'Getting Started' competitions are great for beginners because they give you a low-stakes environment to learn, and they are also supported by many community-created tutorials.

Step 5: Compete to maximize learnings, not earnings.

With that foundation laid, it's time to progress to 'Featured' competitions. In general, these will require much more time and effort to rank well.

For that reason, we recommend picking your battles wisely. Enter competitions that will expose you to techniques and technologies that align with your long-term goals.

While prize money is nice, the more valuable (and reliable) reward will be the skills you'll develop for your career.

Tips for Enjoying Kaggle

Finally, we'll cover our 7 favorite tips for making the most out of your time on Kaggle.

Tip #1: Set incremental goals.

If you've ever played an addicting video game, you'll know the power of incremental goals. That's how great games get you hooked. Each goal is big enough for a sense of accomplishment, yet realistic enough to be within reach.

Most Kaggle participants will never win a single competition, and that's completely fine. If you set that as your very first milestone, you may feel discouraged and lose motivation after a few tries.

Incremental targets make the journey more enjoyable. For example:

Make a submission that beats the benchmark solution.

Score in the top 50% in one competition.

Score in the top 25% in one competition.

Score in the top 25% in three competitions.

Score in the top 10% in one competition.

Win a competition!

This strategy will allow you to measure your progress and improvement along the way.

Tip #2: Review most voted kernels.

Kaggle has a cool feature in which participants can submit "kernels," which are short scripts that explore a concept, showcase a technique, or even share a solution.

When you start a competition or when you hit a plateau, reviewing popular kernels can spark more ideas.

Tip #3: Ask questions on the forums.

Don't be afraid to ask "stupid" questions.

After all, what's the worst thing that could happen? Maybe you get ignored... and that's all.

On the other hand, you have plenty to gain, including advice and coaching from more experienced data scientists.

Tip #4: Work solo to develop core skills.

In the beginning, we recommend working alone. This will force you to tackle every step of the applied machine learning process, including exploratory analysis, data cleaning, feature engineering, and model training.

If you start teaming up too early, you could miss opportunities to develop those cornerstone skills.

Tip #5: Team up to push your boundaries.

With that said, teaming up in future competitions can be a great way to push your boundaries and learn from others. Many past winners have been teams who joined forces to combine their knowledge.

In addition, once you master the technical skills of machine learning, you can collaborate with others who may have more domain knowledge than you do, further expanding your opportunities.

Tip #6: Remember that Kaggle can be a stepping stone.

Remember, you're not necessarily committing to be a long-term Kaggler. If you find out that you dislike the format, then it's no big deal.

In fact, many people use Kaggle as a stepping stone before moving onto their own projects or becoming full-time data scientists.

This is another reason to focus on learning as much as you can. For the long run, it's better to target competitions that will give you relevant experience than to chase the biggest prize pools.

Tip #7: Don't worry about low ranks.

Some beginners never start because they're worried about low ranks showing up in their profile. Of course, competition anxiety is a real phenomenon, and it isn't limited to Kaggle.

However, low ranks are really not a big deal. No one else will judge you because they were all beginners at one point.

Even so, if you're still really worried about low rankings in your profile, you could also create a separate practice account for learning the ropes. Once you feel comfortable, you can start using your "main account" to build your trophy case.

(Again, this is totally unnecessary!)
